Development and efficiency of an acute knee trauma list.

Following acute knee trauma some patients will require urgent arthroscopy. Traditionally surgery is undertaken as in-patient on the general trauma list. This system leads to blockage of beds, repeated starving of the patient and out-of-hour's surgery in many cases. We introduced a dedicated Day Surgery knee trauma list (KTL) to reduce in-patient admissions, waiting time and cost. The typical indications for urgent knee arthroscopy are locked knees secondary to meniscal tears, loose bodies or cruciate ligament ruptures; acute osteochondral fractures; and children with acute meniscal tears. This retrospective review compares the study group: patients on the knee trauma list during the first 8 months following introduction, and the control group: patients on the general in-patient trauma list over a similar period immediately prior to implementation of the new list. There were 49 patients in the control group with an average stay in hospital of 2.5 days. Out-of-hour's operations were performed in 13 patients and 3 patients required a repeat arthroscopy. Fifty-three patients were treated in the knee study group. The significant operations were meniscal repair in 7, fixation of osteochondral fragments in 3. None of the patients required overnight stay. Control group patients were more likely to have surgery performed by inexperienced non-specialist knee surgeons, whereas specialist knee surgeons staffed the knee trauma list. Specialist surgeons were available to staff the knee trauma list. As the majority of the control group had spent an average of 2.2 nights in hospital, there has been considerable savings to the hospital. Introduction of the Day Surgical Knee trauma list has reduced unnecessary admissions per week; episodes of prolonged starving, cost and have improved patient satisfaction and management.

Osteonecrosis of the medial tibial plateau: a case report.

Medial tibial plateau osteonecrosis is a disease that lacks distinguishing signs and symptoms, especially in the early stage, and requires clinicians to exercise a high degree of suspicion to prevent disease progression. We present a case of spontaneous osteonecrosis of the medial tibial plateau in a 59-year-old woman. Within 5 months of the onset of symptoms, the entire medial tibial plateau collapsed down into the metaphyseal region, causing severe varus deformity, instability, and inability to walk without crutches and a hinged knee brace. Initial symptoms of medial joint line pain and generalised swelling of the knee were attributed to early degenerative changes. Subsequent radiographs were misinterpreted as simple medial compartment arthritis. Due to severe bone loss and significant lateral collateral ligament attenuation, a total joint arthroplasty was required, using a stemmed tibial component with medial metal block and bone graft augmentation. The speed of bone collapse and the extension into the metaphysis, requiring complex joint arthroplasty, makes this case unique.

Association between anatomical features and anterior knee pain in a "fit" service population.

Anterior knee pain and overuse sports type injuries have been associated with anatomical factors. Specific diagnosis in knee pain is difficult, most service patients are grouped together as "Patello-Femoral Stress Syndrome". Knee pain incidence within the service population is unknown, but thought to be greater than those presenting to General Practitioners. 293 active duty service men (100 Army and 193 Royal Navy) were interviewed and examined in relation to their knees. 138 measurements were made on each subject. 118 admitted to knee problems. Six had specific diagnoses, ranging from patellar tendonitis to ACL deficiency (with marked anterior instability). The remaining 112 individuals formed the study group and examination findings were compared with the 175 without Patello-Femoral Stress Syndrome. The results have been analysed to determine normal ranges and predictors of knee pain. Age, years in the military and results of patello-femoral compression tests were consistently significantly different between the groups. This survey provides useful information on normal values at examination. Q angle measurement was a poor predictor of knee pain. There was no clinically detectable anatomical variant that correlated with the Patello-Femoral Stress Syndrome. There was poor correlation between Tegner activity score and the perceived limitation on sport or work, as assessed on a visual analogue scale.

Patterns of illness and injury encountered in amateur ocean yacht racing: an analysis of the British Telecom Round the World Yacht Race 1996-1997.

OBJECTIVES: To quantify the incidence and type of medical problem arising during an amateur circumnavigation yacht race, the BT Global Challenge. METHODS: All cases from 14 participating yachts in a confidential medical log completed by an appointed medic were reported. RESULTS: A total of 685 cases were reported, of which 299 (43.6%) were injuries and 386 (56.4%) illnesses. The subtype of injury, illness, and three evacuations at sea are described. CONCLUSION: Injury and other forms of medical problem are relatively common in an amateur long distance ocean yacht race. Most can be adequately managed at sea, provided that optimal communication, training, and equipment are provided and maintained.
